James Randi was a Canadian-American stage magician, author and scientific skeptic who extensively challenged paranormal and pseudoscientific claims. He was the co-founder of the Committee for Skeptical Inquiry (CSI), and founder of the James Randi Educational Foundation (JREF). Randi began his career as a magician under the stage name The Amazing Randi and later chose to devote most of his time to investigating paranormal, occult, and supernatural claims. Randi retired from practicing magic at age 60, and from his foundation at 87.
Numerology is the belief in an occult, divine or mystical relationship between a number and one or more coinciding events. It is also the study of the numerical value, via an alphanumeric system, of the letters in words and names. When numerology is applied to a person's name, it is a form of onomancy. It is often associated with astrology and other divinatory arts.
The biorhythm theory is the pseudoscientific idea that peoples' daily lives are significantly affected by rhythmic cycles with periods of exactly 23, 28 and 33 days, typically a 23-day physical cycle, a 28-day emotional cycle, and a 33-day intellectual cycle. The idea was developed by Wilhelm Fliess in the late 19th century, and was popularized in the United States in the late 1970s. The proposal has been independently tested and, consistently, no validity for it has been found.
Synchronicity is a concept introduced by analytical psychologist Carl Jung "to describe circumstances that appear meaningfully related yet lack a causal connection." Synchronicity experiences refer to one's subjective experience whereby coincidences between events in one's mind and the outside world may be causally unrelated, yet have another unknown connection. Jung held this was a healthy function of the mind, that can become harmful within psychosis.
Uri Geller is an Israeli-British illusionist, magician, television personality, and self-proclaimed psychic. He is known for his trademark television performances of spoon bending and other illusions. Geller uses conjuring tricks to simulate the effects of psychokinesis and telepathy. Geller's career as an entertainer has spanned more than four decades, with television shows and appearances in many countries. Magicians have called Geller a fraud because of his claims of possessing psychic powers.
11 (eleven) is the natural number following 10 and preceding 12. It is the first repdigit. In English, it is the smallest positive integer whose name has three syllables.
18 (eighteen) is the natural number following 17 and preceding 19.
In recreational mathematics, a repdigit or sometimes monodigit is a natural number composed of repeated instances of the same digit in a positional number system. The word is a portmanteau of "repeated" and "digit". Examples are 11, 666, 4444, and 999999. All repdigits are palindromic numbers and are multiples of repunits. Other well-known repdigits include the repunit primes and in particular the Mersenne primes.
Ray Hyman is a Professor Emeritus of Psychology at the University of Oregon in Eugene, Oregon, and a noted critic of parapsychology. Hyman, along with James Randi, Martin Gardner and Paul Kurtz, is one of the founders of the modern skeptical movement. He is the founder and leader of the Skeptic's Toolbox. Hyman serves on the Executive Council for the Committee for Skeptical Inquiry.
A debunker is a person or organization that exposes or discredits claims believed to be false, exaggerated, or pretentious. The term is often associated with skeptical investigation of controversial topics such as UFOs, claimed paranormal phenomena, cryptids, conspiracy theories, alternative medicine, religion, or exploratory or fringe areas of scientific or pseudoscientific research.
Spoon bending is the deformation of objects, especially metal cutlery, purportedly by paranormal means. It is a common theme for magic tricks, which use a variety of methods to produce the effect. Performers commonly use misdirection to draw their audience's attention away while the spoon is manually bent. Another method uses a metal spoon that has been prepared by repeatedly bending the spoon back and forth, weakening the material. Applying light pressure will then cause it to bend or break.
Robert Todd Carroll was an American author, philosopher and academic, best known for The Skeptic's Dictionary. He described himself as a naturalist, an atheist, a materialist, a metaphysical libertarian, and a positivist. In 2010 he was elected a fellow of the Committee for Skeptical Inquiry. He was a professor of philosophy at Sacramento City College from 1977 until his retirement in 2007.
A coincidence is a remarkable concurrence of events or circumstances that have no apparent causal connection with one another. The perception of remarkable coincidences may lead to supernatural, occult, or paranormal claims, or it may lead to belief in fatalism, which is a doctrine that events will happen in the exact manner of a predetermined plan. In general, the perception of coincidence, for lack of more sophisticated explanations, can serve as a link to folk psychology and philosophy.
The law of truly large numbers, attributed to Persi Diaconis and Frederick Mosteller, states that with a large enough number of independent samples, any highly implausible result is likely to be observed. Because we never find it notable when likely events occur, we highlight unlikely events and notice them more. The law is often used to falsify different pseudo-scientific claims; as such, it is sometimes criticized by fringe scientists.
A psychic reading is a specific attempt to discern information through the use of heightened perceptive abilities; or natural extensions of the basic human senses of sight, sound, touch, taste and instinct. These natural extensions are claimed to be clairvoyance (vision), clairsentience (feeling), claircognisance and clairaudience (hearing) and the resulting statements made during such an attempt. The term is commonly associated with paranormal-based consultation given for a fee in such settings as over the phone, in a home, or at psychic fairs. Though psychic readings are controversial and a focus of skeptical inquiry, a popular interest in them persists. Extensive experimentation to replicate psychic results in laboratory conditions have failed to find any precognitive phenomena in humans. A cold reading technique allows psychics to produce seemingly specific information about an individual from social cues and broad statements.
Guy Lyon Playfair was a British writer, best known for his books about parapsychology and his investigation of the Enfield poltergeist.
Telekinesis is a hypothetical psychic ability allowing an individual to influence a physical system without physical interaction. Experiments to prove the existence of telekinesis have historically been criticized for lack of proper controls and repeatability. There is no reliable evidence that telekinesis is a real phenomenon, and the topic is generally regarded as pseudoscience.
The Gore effect or Al Gore effect refers to coincidence between occurrences of unseasonably cold weather and some events associated with global warming activism, particularly those attended by former Vice President of the United States and Nobel Peace Prize recipient Al Gore, which was created and "amusedly" used by global warming deniers.
Cornelis "Kees" de Jager was a Dutch astronomer who specialized in predicting solar variation to assess the Sun's impact on future climate. He was the General Secretary of the IAU from 1967 to 1973 and former director of the observatory at Utrecht. He was a fellow with the Committee for Skeptical Inquiry and played an important role in the European skeptical movement as the first chairman of both Stichting Skepsis and the European Council of Skeptical Organisations.
The look-elsewhere effect is a phenomenon in the statistical analysis of scientific experiments where an apparently statistically significant observation may have actually arisen by chance because of the sheer size of the parameter space to be searched.
